Microlithography, nanolithography, and stamping methods are used. The identificationfeatures can be positive protrusions or negative indentations with respect to the surface.The identification regions can comprise bar codes and holograms. DPN printing or otherlithographies such as electron beam lithography, optical lithography, or nanoimprintlithography can be used to prepare stamps, which are then used to prepare theidentification features. Redundant patterns can be formed. The invention is useful forcounterfeit prevention. An apparatus for stamping the identification features is alsodescribed.
